To all whom. it ',fiov'g/ cof/leem:

Be it known that l, ons M. Jer, e citizen of the United- States, residui;7 et New York, inthe county of New York end State oi New York, have invented certain ncvv end useiul improvements in CircuitControllers for Electric Motors, oi which speciiicetion.

My invention relates to s cuit controller for electric motors, end hes i i its object to provide e simple and effective inc-(ins for eccoinplishing` this purpose, and to this end my invention consists in e cf rit controller embodying` the general eeti'es ci construction, errengenient ,oi parts, sind havingy the general inode of operati-en substantially hereinafter rnore perticulsirfljr set forth.

Referring` to the accompanying; dren/ings wherein I heve .illustrate/.l e preferred einbodiment of my circuit controller, and shown one application thereo-Figure l is an ele vetion of e circuit controller showing it :ipplied to e, printing, telegraph, some perte of which letter ere shown in elevation end some in section; Fig. 2 is e side view ol the circuit controller; and Fig. 3 is e. transverse section on the line 3 3 of Fig. 2,

@ne of the ohiects of my present invention is to provide en electro-rnegneticolly open eLted circuit controller ier electric inotors which is adapted Jfor many and various uses, and which is especieilj,T adapted for use in connection With printing telegrephs. l have shown in);7 invention in this connection, elthough it will he understood that the invention een he used in other connections and relations, it being constructed. end en ranged hy those skilled in the crt to adept it for the particule-r use igor which it is intended.

It will be readilyv understood that in opereting,r mechanism loven electric motor, it is often desirable to have some ineens Whereby the circuit oi' the motor een he controlled, especially to maire end breek the circuit, and in many csi-ses it is desirel'ile to provide outoinetic ineens controlled by seine operative port of the mechenisin driven by the inotor which shall, under certain circumstances, control the circuit of the inotor drivingA such mechanism in accordance with the conditions or operation of the inechenisrn driven the following is e,

by the inotor, This especiellj,r desirable in printing telegrephs, end it is for that reason that l have chosen to illustrate my invention in connection Ywith e printing teleg sph ine zhenisin.

inthe present instinico, i herve shown niv invention :is connected and cooperatingy vvith e printing telegraph receiver ol? the `general type disclosed in niv Potent No. 780,664, deted Jennery 2e, i905, end l have lillustrated enough ci such telegraph receiver to show how my invention een he applied end used in connection therewith.

in the accompanying drawing, l is e bese hr1-vin@ en upright or standard 2 forming port oi e.. i nc supporting the operative ports oi e printing telegraph receiver; and M represents en electric motor, in this instance directly connected to e shaft 33 mounted on the hase end having hearing in the bracket 57, and this may be seid to constitute the mein operating shaft oi the telegraph receiver, from which the various ports receive motion. It is not deemed necessary to illustrete eli these parte, es they ere iully disclosed ond described in my prior patent, 1tout i will state that G will represent the type v-:heel shaft of that instrument on which worin vwheel 73 nieshimg with :rworin 77 loose upon -the shaft hut connected to the .shaft through 'e clutch 79, spring 78 and coller SU, -while 61 may represent the type wheel carriage moving shaft, which is driven frein e worin 39 ou the shaft 33 nieshin with o. worin wheel 40. .The gear wheel 82 loose on the sheilt :ind is adopted to operete some other part of the telegraph receiver ond is driven 'from the shaft 33 through the'mediuin of the clutch 83, spring Se and coller S5. present .invention and are simply shown, es typical of e. mechanism in connection with which my circuit controller is adapted to he utilized, i @vill not, therefore, describe the details oi construction and operation of .these parts herein.

Mv improved controlling device comprises has@ or support A, upon which ere. conveniently mounted the operative parts; end upon the stud B is mounted e wornijivheel C which is connected to he operated by the motor, the circuit ofy Whichis to be con- These devices forni no part of the trolled. In the present instance, connected to the worm C is ii worin wheel adapted to engage :i worin 21 connected to a gear 22, engaging a gear 23 Conveniently formed on the collarv 8O of the shaft 33, 'whereby the circuit controller is operated from the inotor M through its shaft 33 and the iiiterinedis-te Connections thus described. it -will oe iinderstood that theseI intermediate connections will Vary in iiccordiinee with t-l position :ind relation of the cir-ei 1'- contijofeif to the motor, the circuit of which it is to control, and those described i typical onlyY and are so arianflcd that 'the worin is d or from the motor tliroiigh intermediate connections. preferably at a reduced speed `with relation to the speed of the shii'l'i 33 of the motor.

The erin E is also, hissed with relation to the armature hy any siiitshle Ineens, and l have shown .ai coiled spring e, one end of rfhich is connected to the arm E, sind the other of which is coiled around and secured to s sind a mounted on the armature lever. The tendency of this spring is to linen the erin l) and rivcn hy the Worin :it or near one end of the groove thereof.
